Embodiment
Below in conjunction with accompanying drawing and by specific embodiment technical scheme of the present invention is elaborated, in following examples with SP (information content provider) as professional third-party preferred embodiment is provided.
For the WAP business, the stand-by period of user experience (terminal is sent request to the time interval of receiving response) is important performance index.WAP gateway of the present invention adopts distributed arrangement on each service processor cache module to be set in order to shorten the experience time and to reduce network congestion in the present embodiment.Also can select to adopt centralized layout's cache module, accept the buffer memory control of each WAP gateway, no longer describe in detail herein.Also increase in the present embodiment to be used for handling the Business Processing thread of buffer memory special, as shown in Figure 3.The caching process mechanism that the present invention adopts is with reference to existing Squid trafficwise.Squid is an a more outstanding Application Agent software under the Linux environment, and the configuration of high-speed cache and flexible strategies can be set.The existence of buffer memory makes network speed be greatly improved, its principle is for behind address of a user capture, Squid deposits this address contents on local internal memory or the hard disk, when next user visits again this address, if Squid finds this address contents and do not change, just directly fetch data and issue the user, so speed has obtained large increase from this locality, reduced the network bandwidth simultaneously and taken, this makes other access request obtain high speed processing becomes possibility.A plurality of Squid servers can cascade up, and are configured to a greater and faster proxy caching group.Squid also supports agreements such as FTP, GOPHER, SSL and WAIS simultaneously.What the present invention was different with Squid is, WAP gateway does not need used respond style is all carried out buffer memory (for example: MMS just can not be used buffer memory), and for fear of the bottleneck of caching function to bringing on the WAP gateway performance, can be configured the response message of a restriction WAP gateway SP that buffer memory SP visiting frequency is the highest by the foreground O﹠M.The specific implementation of the caching function that increases in the WAP gateway also comprises following ins and outs:
1.WAP if the cache module of gateway adopts distributed arrangement, the performance bottleneck that can avoid centralized layout to exist;
2.WAP the cache file structure in the gateway can be used for reference the file structure in the squid software;
3. Round-Roubin (polling dispatching) method is adopted in the selection of cache file root, finds the storage root of a suitable catalogue as cache file.The principle of polling dispatching method is each time the server of distributing in turn from user's request in the inside, since 1, up to N (internal server number), restarts circulation then.The meaning here is exactly after business is received the response of SP, if do not find that in local cache this response was buffered, then adopts the Round-Roubin algorithm, finds a suitable root, and buffer memory is carried out in this response.
4. the name of subpath and cache file name adopts BitMap (bitmap) algorithm to determine the name of cache file, utilizes the computational algorithm of existing file path to obtain the path of depositing of cache file then.Metadata is the data of data of description, often can use metadata in file system, volume management system, fast photographic system, utilizes metadata information to come the feature of data of description.The form of metadata information is various, and metadata has different forms in the different systems.Caching process of the present invention is similar to fast photographic system, and the amount of information of metadata is bigger, and can increase along with reducing of management data block granularity, can adopt the mode of bitmap (bitmap) to store such as the such metadata of file system.
According in the http protocol to the characteristics of dependency rule and the WAP gateway own service of cache, WAP gateway judges whether to carry out buffer memory;
6. when spatial cache uses totally, use LRU (the recent minimum use of least recently used) algorithm to judge whether a buffer memory should be deleted.
Below in conjunction with attached Fig. 1 and 2 detailed enforcement of the present invention is described:
Fig. 1 receives the handling process after the user asks after illustrating that WAP gateway increases buffer process module.
If 1 WAP gateway is received user's solicited message, judge whether this request allows to use buffer memory earlier, if do not allow, then the WAP gateway structure is asked to SP;
2 otherwise, according to the URL information of user request, calculate its MD5 value as index value, search whether there is this index in the local internal memory;
3, judge whether the cache information of this index available, if available, then notifies the buffer memory process, upgrade the file mapping information in the buffer memory, and by WAP gateway forwarding cache information to terminal; Otherwise the structuring user's request is transmitted to SP.
After Fig. 2 illustrates that WAP gateway increases the cache module, the handling process after receiving the SP response.
1, WAP gateway is received the SP response, goes to the caching process process;
2, the buffer memory process judges whether need allow to carry out buffer memory;
If 3 allow, judge whether disk space allows to store, if for being, cache information then; Otherwise, adopt lru algorithm, the information that the deletion visit is minimum, new cache contents is preserved in the release disk space, upgrades the map information in the local internal memory
If 4 do not satisfy the cache bar part, then directly the SP response is transmitted to professional other treatment progress.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
